This invention relates to improvements in coin selecting devices whichmay be used withcoin actuated mechanisms.

'I'he general object of the invention is to provide an improved coinselector device which will separate spurious coins, slugs or otherobjects from good coins of the denomination intended to actuate thedevice with which it is associated.

pther objects and the advantages of this invention will be apparent fromthe following description taken in connection with the accompanyingdrawings wherein:

Referring to the drawings by reference characters I haveA indicated myimproved coin selector generally at Ill. The device I0 is especiallyadapted for use in combination with a coin actuated mechanism, whereintwo coins of different denominations are required to actuate themechanism which in this instance are a dime and a nickel. The presentinvention is an improvement over that shown in application Serial No.617,356, led June 15, 1932, by William L Gilchrist and Wiuiam H.Hoofnagie.

As shown the device I0 comprises a nickel selecting unit I2 and a dimeselecting unit I3. The nickelselecting unit I2 comprises a base memberi4 having a cover plate I5 secured there- .40 to by screws I6 and whichis retained in` spaced relation to the base I4 by raised portions on thebase such as indicated at I1 toform a chamber I8. The base I4 and thecover plate I5 are made of non-ferrous metal and are preferably diecast. Adjacent the top'of the device I4 I provide an entrance raceway 20which is formed by a pair of spaced rearwardly and downwardly inclinedguide portions 2I and 22. The entrance raceway 20 is adapted to directcoins into a forwardly and downwardly inclined raceway 23 which isformed by a pair of spaced -guide portions 24 and 25. The raceway 23 isadapted to direct coins into a vertical raceway 26 which on the forwardside includes a guide portion 21 which includes a 5 5 shoulder 21'.

A portion of the bottom of the raceway 23 is formed by an upper face ofa b ar magnet 281 which at its forward end terminates at the juncture ofthe raceway 23 and the raceway 26 in a rounded end portion 29. Theraceway 26 communicates with a raceway 30 which includes a rearwardlycurved section 3I and a straight rearwardly and downwardly inclinedsection 32. 'Ihe lower side of the curved section 3I of the raceway 30is formed by a guide portion 33 and the upper side is formed by a guideportion 34 which has a` forward face 34 and the lower portion ofthestraight section 32 is formed by a guide portion 35. The guide portions33 and 35 are preferably bevelled downward towards the cover plate asindicated at 36 (see Fig. 2) to urge coins towards a magnet to bepresently described.

Good nickels upon leaving the raceway 30 pass through a raceway'31 andenter a vertical exit raceway 38. The bottom of the raceway 31 is formedby avselector device 39 which includes a dividing point 4Il. Theselector device 39 is pivotally mounted on the base I 4, as indicated at40',- so that it may be swung and adjusted and is adapted to be firmlyretained in an adjusted position by a screw 40".

Spurious coins upon leaving the raceway 30 fall into a downwardly andforwardly inclined raceway 4I which directs them into a vertical raceway42. The bottom of the raceway 4I is formed by a guide portion 43 and theforward side of the raceway 42 is formed by a guide por-v tion 44. y

Adjacentthe juncture of the raceways 23 and 26 I provide a rearwardlyand downwardly inclined raceway 45 the top of which is formed by a guideportion 46 and the bottom by a guide portion-41 with the guide portionterminating adjacent the curved portion 29 of the magnet 28. The raceway23 directs ferrous coins into a downwardly and forwardly inclinedraceway 48 one side of which is formed by a guide portion 48 and theother side by a guide portion 50.

Adjacent the lower end of the raceway -48 I` provide an aperture 5I inthe cover plate I5 (see Fig. 4). Furthermore, adjacent the lower end ofthe raceway 48 I provide an abutment portion 52 which1its an aperture inthe cover plate I5 and'which includes an inclined surface 53 whichadapted to direct coins out oi.' the device I2 through the aperture 5Iin the cover plate I5.

Intermediate the length of the entrance raceway 20 I provide anelongated aperture 54 in vplate I5. The plate clined rearwardly and thebase I4 and in the raceway 23 I provide a similar aperture 55 in thebase.

Adjacent the straight section 32 of the raceway 30 I provide a horseshoe magnet 56, the poles 51 and 58 of which are arranged in holes in aplate 58a which ts in a slot 58b in the cover 58a has'end ribs 58c andside ribs 58d thereon. The poles 51 and 58 are positioned across theraceway 30 at approximately right angles thereto with the faces of thepoles and the face of the plate 58B flush with the inner face of thebase |4. Opposite the magnet 56 I provide a similar horse shoe `magnet59, similarly mounted and with the poles 60 and 6I positioned across theraceway 30 similar to the poles of theY magnet 56. The faces of thepoles 60 and 6| and the plates 58a thereof are fiush with the inner faceof the cover plate I5 as clearly shown in Fig. 3. The poles of themagnets 56 and 59 are positioned in opposed relation, that is the northpole of the magnet 56 is opposite the south pole of the magnet 59 andvice versa.

The dime selecting unit I3 like the nickel selecting unit I2 comprises abase 62 having a cover .plate 63 thereon which is retained in spacedrelation from' the base by raised portions on the base such as indicatedat 64 to form a chamber 65. The base 62 and the cover plate 63 are madeof non-ferrous metal and are preferably die cast. Adjacent the top ofthe device I3 I provide a rearwardly curved entrance raceway 66 which isformed by a pair of spaced guide portions 61 and 68. Themraceway 66directs coins into a rearwaidly and downwardly inclined raceway 69 thetop of which is formed by a guide portion 10 and the bottom by a guideportion 1|. The raceway 69 directs coins into a raceway 12 which isindownwardly at a sharper slope than the raceway 69 and one side ofwhich is formed by a guide portion 13.

Adjacent the juncture of the raceway 69 and the raceway 12 I provide amagnet member v14 the end of which at the juncture of the raceways 69and 12 is rounded as at 15 and a portion of the magnet 14 adjacent thejuncture of the raceways 69 and 12 forms a part of the bottom of theraceway 69, as at 16.v The raceway 12 directs coins into a downwardlyand forwardly inclined raceway 11 the sides of which are formed byspaced guide portions 18 and 19. The guide portion 19 includes aShoulder 19.

The raceway 11 communicates with a raceway which includes a forwardlycurved section 8| and a straight', forwardly inclined, section 82. Oneside of the curved section 8| of the raceway 80 is formed by a'guideportion 83 and the opposite side by aguide portion the straight sectionis formed while the bottom is tion 86. The guide portion tion 8| of theraceway 80 is towards the cover plate as indicated at 84' (see Fig. '1).Ciood dimes upon leaving the raceway 80 fall into a forwardly anddownwardlyinclined by a guide portion 84 of the curved secracewayY 81which directs them into a verticalexit raceway 88. The bottom of theraceway 81 is formed byV a guide portion theraceway 88 is formed by aguide portion |00. The front of the raceway 88 is formed by a guidemember |0I which is separate from the base 62 and is loosely mounted onthe base by rivets |02. By loosely mounting the guide member |0| coinsstriking this guide member will be prevented from rebounding therefromover the separating point |25 into the coin chute |03.

84 and the top of formed by a guide porpreferably bevelle'd 99 and therear of A Some spurious coins upon leaving the raceway 80 fall into arearwardly and downwardly inclined raceway |03 which directs them into avertical exit raceway |04. The bottom of the raceway |03 is formed by aguide portion |05 and the rear of the raceway |04 is formed by a guideportion |06.

Other spurious coins upon leaving the raceway 80 strike a selectordevice |01 and run down this selector device and fall downward andstrike a selector device |08 and are directed into a raceway |03. Eachof the selector devices |01 and |08 is pivotally mounted on the base 62as indicatedat |09 and ||9 so that they may be adjusted and are adaptedto be firmly clamped in adjusted positions by screws I I0.

Adjacent the juncture of the raceway 69 and 12 I provide a forwardly anddownwardly inclined raceway I2 the top of which is formed by a, guideportion ||3 and the bottom by a guide portion ||4, and a portion of thebottom of the magnet 14 as indicated at I|5. The raceway ||2 directsferrous coins into a rearwardly and downwardly inclined raceway ||6 theforward side of which is formed by a guide portion ||1 and the rear sideby a guide portion I |8.

Adjacent the straight section 82 of the raceway 80 I provide a horseshoe magnet |20 which is set in a plate |20a which is similar to theplate 58e, previously described. The poles |2| and |22 of the magnet |20are positioned across the raceway 80 at approximatelyy right anglesthereto with thev faces of the poles flush with the inner surface of thecover plate 63 as clearly shown in Fig. '7. Set into the base 62opposite the magnet |20 I provide an armature plate |23, theinner faceof which is flush with the inner face of the base and-the outer face isush with the outer face of the base.

When the device I0 is operatively assembled the nickel unit I2 and thedime unit I3 are positioned with their respective bases back to back andare retained in this position in any desired manner. When the units I2and I3 are thus assembled the armature plate |23 of the unit I3vcompletely covers the aperture the unit I2 and partially covers theaperture 55 in the base of the unit I2, as clearly shown in Fig. 1.

Good nickels entering the entrance raceway 20 of the nickel unit I2 passdownward through the raceway into the raceway 23 thence into and throughthe raceway 26 and strike the forward face 34 0f the guide portion 34and then pass beneath the shoulder 21' thus before they pass into theraceway 30. As a nickel passes the aperture 54 in the raceway 20 and theaperture 55 in the raceway 23 it is slowed down somewhat by the flux eldproduced by the magnet |20. In the raceway 30 the nickel passes betweenthe poles of the magnets 56 and 59 and the flux field again alters thevelocity of the coin according to its magnetic contents so that@ goodnickel enters the raceway whence it passes into the exit raceway 38.

Iron and steel disks entering the raceway 20 pass downwardly thereininto the raceway 23 54 in the base of being slowed down through whichthey roll to the rounded end 29 of CSi f' roll into the raceway 12 Someother non-ferrous spurious disks after passing through the entranceraceway 20 pass x.through the raceways 23 and 26 into the raceway 30. Asthese spurious disks pass through the magnetic field between the polesof the magnets 56 and 59 their velocity is decreased to such an extentthat as they leave the raceway 30 they do not have suicient speed topassover the dividing point 40 of the selector/39 'so therefore fall intothe raceway 4| whichdirects them intothe raceway 42.

The-raceway v38 into which good' nickels are directed may communicatewith a suitable coin chute which in turn will direct the nickels to thecoin actuated mechanism with which the device is associated. spuriouscoins leaving the raceways 42'and 48 may be directed into suitable coinlchutes which may either direct the spurious disks 'out of the machinewith which the device is associated or into a suitable receiver.

Good dimes upon entering the entrance raceway 66 of the dime unit I3pass therethrough into the raceway 68 which directs them into theraceway 12 from which they pass into the raceway 11 which directs theminto the raceway 80. As the dimes pass from the raceway 11 into theraceway 80 they strike the shoulder 19' which momentarily stops themcausing them to' joggle so that each coin enters the curved section 8|of the raceway 80 at approximately .the same speed. As a dime passesbetween the poles of the magnet |20 and the armature plate |23 it passesthrough the flux field between the poles |2| and |22 and the armatureplate |23 and is retarded suiiiciently so that in its fall it does notstrike the dividing point |24 of the selector |01 but does not retard itsuiiciently to cause it to strike the dividing point |25 ofthe selector|08. 'I'hus the retardation of the dime is such that after leaving theraceway l8|! it falls into the raceway 81 which directs it into the exitraceway 88. y Iron and steel disks entering the entrance raceway 66 passtherethrough into the raceway 69. which directs them into the, raceway12. As they the magnet 14 attracts them into the raceway 2 through whichthey roll into the raceway I6 down which they fall into the raceway |03which directs them into the raceway |04.

Some other non-ferrous spurious disks after entering the entranceraceway 66 are directed through the raceways 69, 12 and 11 into theraceway 80. As these spurious disks pass through the magnetic fieldbetween the poles of the .magnet |20 and the armature plate |23 theirvelocity is retarded sufliciently to cause them to fall straightdownward into the raceway |03 and thence into the raceway |04.

'I'he raceway 88 into which good dimes are directed may communicate witha suitable coin chute which in turn will direct the dimes to the coinactuated .mechanism with which the device is associated. Spurious coinsleaving the rac'eway |04 may be directed into suitable coin chutes whichmay either direct the spurious disks out of the. machine with which thedevice isassociated or into a suitable receiver. l

In Fig. 5 I show a sizing device which is indicated generally at |25.This sizing device includes a chute |26 through which coins pass beforeentering the upper end of chute 66. A member |21 is pivoted as at |28and is provided with a weighted portion |29 so that the member normallyassumes the position shown in Fig. 8. A small light weight coin enteringthe chute |26 will not rock the member |21 and consequently will passover the chute 66 and over the separating point |30 which is oil/the tipof the chute 61. Thus, this small light weight coin' will not enter thechute I66. A proper coin however will pivot the member |21 about itspivot |28 and will cause this proper-sized coin to enter the chute 66and thus pass to the coin selecting mechanism.

From the foregoing description it will be apparent that I have provideda novel coin selecting device which is simple in construction and highlyemcient in use;
